Geophysical report

Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

B. Proton Events
None.
C. Geomagnetic Activity Summary
The geomagnetic field began the period at an quiet levels, before the onset of CME impacts. The second period observed active levels, then a period of major storm levels followed by a period of minor storm levels. Activity increased further to severe storm levels for the remaining periods of the day.
